A fast-set, plural component, spray applicator (12) includes a stationary mix chamber (48) to eliminate dynamic metal-to-metal high pressure fluid sealing. The stationary mix chamber (48) mixes the plural components before dispensing the mixed components from the spray applicator.

A kit for a spray gun including a sleeve delimiting an inner volume provided to contain a pressurized fluid, the sleeve being configured to be connected to a main body of a spray gun, the sleeve having a radial periphery delimiting a fluid outlet of the sleeve and at least one orifice emerging on the radial periphery and fluidly connecting the inner volume and the radial periphery, a connector having an intake end connected to the fluid outlet and a connecting end suitable for being connected to a cup so as to fluidly connect the cup to the inner volume of the sleeve, and a ring surrounding the sleeve and covering the fluid outlet outside the intake end of the connector.

Devices, systems, and methods for mitigating leakage from connectors and tubing of an endoscope system when the connectors and or tubing are disconnected from fluid ports of the endoscope system. A tubing assembly for connecting a fluid line to an endoscope and a fluid source may include an elongate tube having a lumen, a connector coupled to an end of the elongate tube and having a port in fluid communication with the lumen, and a fluid control component configured to selective adjust fluid flow through the lumen and the port. The fluid control component may be located in one or more of a cover for the fluid source, the tubing, the connector, and/or other components in fluid communication with the lumen. The fluid control component may be a valve. The valve may be manually actuated from a closed position to an opened position.

The disclosure presents templates that can be useful in construction. Embodiments of the templates include a face, and two or more indicators. The indicators are located at one or more predetermined intervals on the face, and each indicator defines a window. Each window is of a predetermined length, and each indicator is coded to indicate that each indicator is located at one of the one or more predetermined intervals.

A system for spraying hot-melt adhesive onto glued surfaces comprising a melter to heat hot-melt adhesive, an air compressor, a power and control system and a gun. The gun is connected to the melter by a pipe with screw connectors, through which a hot-melt adhesive being heated flows, and the air compressor by an air pipe with screw connectors through which a pressurized compressed air flows. The gun has a nozzle with a hot-melt adhesive outlet or orifice and a compressed air outlet. The pipe through which flows the hot-melt adhesive having a viscosity between 2500 mPa.Math.s and 7000 mPa.Math.s and a temperature between 120 C. and 200 C., and a density between 0.8 kg/dcm.sup.3 and 1.4 kg/dcm.sup.3, and the air pipe are fitted in an insulating layer of a hose.

Disclosed is an integrated spray machine which comprises a shell, a sprayer assembly, an air pump motor assembly, a battery, a circuit board and a switch, wherein the sprayer assembly comprises a housing, a container and a spray mechanism; the housing is matched with the shell, the container and the spray mechanism are mounted in the housing correspondingly, and the container communicates with a liquid inlet of the spray mechanism; the air pump motor assembly, the battery and the circuit board are all arranged in the shell, the switch is arranged on the wall of the shell, the air pump motor assembly, the battery and the switch are all electrically connected with the circuit board, and an air outlet of the air pump motor assembly communicates with an air inlet of the spray mechanism through an air pipe.

A system includes an electrostatic tool having a cascade that includes electrical components configured to convert a first voltage from an incoming alternating current into an outgoing second voltage at a direct current and a shell configured to cover the electrical components. The shell radially conforms to the electrical components.

A makeup machine includes a multi-nozzle spray head and a plurality of needle valves. The multi-nozzle spray head has a main body and a plurality of nozzles. Each of the nozzles includes an interior chamber and an ejection hole, and the interior chamber is communicated with the ejection hole. The needle valves are disposed in the main body and axially aligned with the ejection holes. The needle valves are configured to be axially movable away from the corresponding ejection holes to open the ejection holes and to be axially movable towards the corresponding ejection holes to close the ejection holes. Further, the needle valves are capable of synchronously or individually moving with respect to the main body.

The disclosure concerns a mixing valve for mixing two coating agent components (e.g. master batch and hardener) to form a multi-component mixture, with two coating agent inlets for supplying the two coating agent components and with two coating agent valves for controlling the coating agent flow through the two coating agent inlets, as well as with a coating agent outlet for discharging the multi-component mixture in a specific outflow direction. The disclosure provides that at least one of the coating agent valves is formed as a rotary slide valve having two plane-parallel valve discs which are rotatable relative to each other about an axis of rotation.

A dosing dispenser system and a dosing dispenser include a slidable control configured to allow a user to select a desired mixing ratio for a product contained in a container attached to the dosing dispenser with a transport medium, such as water, flowing through the dosing dispenser.
